Description

Heat insulation structure for anti freeze of water pipe of multi-unit dwelling}

The present invention relates to a heat insulating structure of water and sewage pipes, and more particularly to a heat insulating structure for freezing the water supply and sewage pipes of a multi-family house configured to prevent the freezing of the water pipe through which the purified and disinfected high water supply water passes.

In general, underground pipe products used in the construction of public housing, wastewater pipe construction, and water supply pipes buried in the ground were mainly made of concrete fume pipes or synthetic resin spiral pipes.

Soil dug to bury underground pipes is used for fill, and underground pipes are often passed through soft ground, and soil is mixed with gravel depending on the area so that the drainage pipe drains smoothly. It is a reality that many tasks are difficult to accomplish.

In addition, the drainage pipe to be dug more deep in the ground while the process for maintaining the drainage gradient as described above is a reality that many problems under the construction site bad conditions.

In addition, the buried drainage pipe is buried in the process of laying the soil to be dug back to the depth of the process, most of the process, because the soil reinforcement is low soil reinforcement, the process of compacting in the buried process This is necessary, and additional equipment is required due to the conditions at the construction site. Therefore, the compaction work should be reinforced on both side walls of the drainage pipes buried in the damaging work to reinforce the external pressure of the drainage pipes.

In addition, the drainage pipe used by laying underground is manufactured to a certain length during manufacture and transportation, and is continuously connected at the construction site to bury it, and the drainage pipe is buried in the ground due to heavy rain, etc. If the connection part is twisted to each other, the problem of water leakage occurs, for this purpose reinforcement of buried soil was often required.

On the other hand, water pipes for supplying water to factories, houses, and various facilities, and sewage pipes for transporting used sewage to remote sewage treatment facilities are buried underground to secure ground space and beautify living environment.

Buried water and sewage pipes, the ground is cut into a sufficient space for seating the structure that connects a plurality of water and sewage pipes having a constant diameter and length in a line, where the water and sewage pipe structure sequentially in the longitudinal direction This is done by burying in earth and sand after being seated.

Looking at the conventional method of embedding simply because digging the ground and put the water and sewage pipe there and then cover the ground again, the construction is easy and widely used. In particular, in urban areas, water and sewage pipes are formed by digging soils located at the periphery of water and sewage pipes to increase the density between the soils and by including concrete or asphalt on the ground where water and sewage pipes are buried. The risk of breakage is minimized.

Referring to this, the water pipe 10 is a large diameter main pipe 12 for transporting a large amount of constant water over a long distance, and branch pipes 14 which are branched from the main pipe and are used for relatively short distance transportation for supplying water to buildings such as homes and offices. ) In this way, the branched pipe body must be provided with a valve 14a so that the water can be interrupted, thereby facilitating the work by the number of steps when replacing the aged water pipe 10 or replacing the valve 14a. .

On the other hand, the water pipe 10 as described above is mainly buried in the ground, conventionally, after digging the ground in the area where the water pipe passes and made a predetermined space with brick or soil, install the water pipe 10 connected to the branch pipe (14). As a structure, since the water pipe around the brick or soil, especially in winter, the freezing wave of the water pipe 10 was generated, it was difficult to properly perform the water supply function.

The first double pipe 110 is a fluid is transported through the hollow inside of the first inner tube member 112, wherein the fluid may be cold water, hot water, oil, gel, and the like, the first double pipe 110 is installed to penetrate both side walls of the housing 140 to be described later.

In addition, the first exterior member 114 is installed so as to surround the outer periphery of the first inner tube member 112, the first outer member 114 is the first inner tube member 112 outside the environment and impact, or pipe It is installed to maintain the temperature of the fluid flowing inside.

2 to 6, a first heating wire is generated between the first inner tube member 112 and the first outer member 114 by the supply of power along the longitudinal direction of the first double tube 110. 116 is embedded in the form of a coil. Here, a vacuum space (not shown) may be further included.

In this case, the power source is electrical energy converted from solar cells collected from a light collecting plate (not shown) for collecting sunlight.

Preferably, the light collecting plate is separately installed at a position close to the water and sewage pipe of the apartment house, and the power source may be a commercial power source used in a home or a factory.

Solar energy is collected by the light collecting plate, and the solar energy is converted into electrical energy through a solar cell to be stored in a storage battery and then supplied to the heating wire 116.

As such, the first heating wire 116 supplied with power generates heat as the temperature of the first double pipe 110 inside the storage housing 140 as a predetermined temperature.

The second double pipe 120 is installed in a direction orthogonal to the first double pipe 110, and the aforementioned fluid is transferred through the hollow interior of the second inner pipe member 122, and the second exterior member 124 is provided. ) Is installed to surround the outer circumference of the second inner tube member 122, the second outer member 124, as described above, the second inner tube member 122 to the outside environment and impact, or to flow inside the tube It is installed to maintain the temperature of the fluid.

Meanwhile, the first and second exterior members 114 and 124 may have a panel shape made of expanded polyethylene and foam rubber and have a self-elasticity. Referring to FIG. Both ends of the inner tube members 112 and 122 which are in contact with each other while being in contact with each other may be fixed by heat fusion or adhesive.

Therefore, the first and second exterior members 114 and 124 block the inside from the outside, and a vacuum space that functions as a buffer and thermal insulation between the first and second exterior members 112 and 122 (Fig. Not shown).
